S-90380A312 Length 1 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior plastic retention with tri-lobe shank design that creates strong, vibration-resistant threads without chipping or cracking materials
• Enhanced corrosion resistance through zinc-plated steel construction for reliable performance in demanding industrial environments
• Optimized drive efficiency with Phillips No. 3 drive that provides secure tool engagement and reduces cam-out during installation
• Maximum holding power achieved through fully threaded design that ensures complete engagement along the entire fastener length
• Reduced assembly stress with thread forming (TRS) technology that displaces material rather than removing it
• Precise installation compatibility with pre-drilled No. 8 holes (0.199" diameter) for accurate placement in plastic components
• Broad application versatility with standard pan head profile that sits flush while providing excellent bearing surface

Professional Applications & Engineering Value

These No. 12 thread forming screws deliver exceptional value in plastic assembly applications where material integrity is paramount. The tri-lobe shank cross-section and thread forming technology work synergistically to displace plastic material without creating chips or stress fractures that compromise structural integrity. Made from zinc-plated steel, these TRS screws provide excellent corrosion resistance while maintaining the strength needed for durable fastening solutions. The Phillips drive system ensures reliable installation in high-volume production environments, reducing the risk of driver slippage and damaged components. These thread forming fasteners are specifically engineered to prevent the common failure points in plastic assemblies, making them ideal for automotive trim, electronic enclosures, and industrial equipment where vibration resistance and long-term reliability are critical requirements.

Specification Summary & Compliance

These thread forming screws feature precise dimensional specifications including No. 12 thread diameter (0.216"), 1-1/4" length, and 11 threads per inch. The TRS (Thread Rolling Screw) design follows industry-standard thread forming principles with tri-lobe shank geometry. Manufacturing compliance includes RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant certifications, ensuring environmental regulatory adherence for global industrial applications. The blunt tip design and standardized pan head profile provide consistent performance across plastic fastening applications while maintaining full compliance with international environmental and safety standards.
